The jack is designed exclusively for jacking
up the vehicle at the jack take-up brackets
built into both sides of the vehicle. To help
avoid personal injury, use the jack only to lift
the vehicle during a wheel change. Never
get beneath the vehicle while it is supported
by the jack. Keep hands and feet away from
the area under the lifted vehicle. Always
firmly set parking brake and block wheels
before raising vehicle with jack.
Do not disengage parking brake while the
vehicle is raised. Be certain that the jack is
always vertical (plumb line) when in use,
especially on hills. Always try to use the jack
on level surface. Make sure the jack arm is
fully seated in the jack take-up bracket. Al-
ways lower the vehicle onto sufficient ca-
pacity jackstands before working under the
vehicle.

325 Practical hints
Battery
Reconnecting the battery
Turn off all electrical consumers.

Connect the positive lead and fasten its
cover2.

Connect negative lead1.

Reinstall the filter box (
page 323).Batteries contain materials that can harm
the environment if disposed of improperly.
Large 12 volt storage batteries contain
lead. Recycling of batteries is the preferred
method of disposal. Many states require
sellers of batteries to accept old batteries
for recycling.
!NEVER invert the terminal connections!!The battery, its filler caps and the vent
tube must always be securely installed
when the vehicle is in operation.
iThe following procedures must be
carried out following any interruption of
battery power (e.g. due to reconnec-
tion):

Set the clock (
page 126).
Vehicles with COMAND*:
See COMAND operator’s manual.


Resynchronize the ESP
(page 282).


Resynchronize side windows
(page 202).


Resynchronize sliding/pop-up
roof* (
page 205).

328 Practical hintsTowing the vehicle
Towing the vehicleMercedes-Benz recommends that the
vehicle be transported with all wheels off
the ground using flatbed or appropriate
wheel lift/dolly equipment. This method is
preferable to other types of towing.When circumstances do not permit the
recommended towing methods, the
vehicle may be towed with all wheels on
the ground or front wheels raised (except
vehicles with 4MATIC) only so far as
necessary to have the vehicle moved to a
safe location where the recommended
towing methods can be employed.
!Use flatbed or wheel lift/dolly equip-
ment with SmartKey in starter switch
turned to position0.
Do not tow with sling-type equipment.
Towing with sling-type equipment over
bumpy roads will damage radiator and
supports.
To prevent damage during transport,
do not tie down vehicle by its chassis or
suspension parts.
Switch off the tow-away alarm
(page 79) and deactivate the auto-
matic central locking (
page 133).
!Vehicles with automatic transmission
and/or 4MATIC:
Do not tow-start the vehicle.!Vehicles with 4MATIC:
Do not tow with one axle raised. Doing
so could damage the transfer case,
which is not covered by the
Mercedes-Benz Limited Warranty.
All wheels must be on or off the ground.
Observe instructions for towing the
vehicle with all wheels on the ground.
!If the vehicle is towed with the front
axle raised (not permissible for vehicles
with 4MATIC), the engine must be shut
off (SmartKey in starter switch
position0 or1). Otherwise the ESP will
immediately be engaged and will apply
the rear wheel brakes.
When towing the vehicle with all wheels
on the ground, the gear selector lever
must be in positionN (manual trans-
mission: gears disengaged) and the
SmartKey must be in starter switch
position2.
When towing the vehicle with all wheels
on the ground or the front axle raised,
the vehicle may be towed only for
distances up to 30 miles (50 km) and
at a speed not to exceed 30 mph
(50 km/h).
